Abstract
The Neoproterozoic Swift Run Formation in the Virginia Blue Ridge forms a discontinuous heterogeneous sedimentary unit that unconformably overlies older basement rocks of the Blue Ridge Complex. This study concludes that the Swift Run Formation is a fluvial deposit, laid down in the low-lying areas of the underlying basement rocks, which, in locations, underwent later faulting and folding. The north to northwest trending structural and isopach contours in the southern part of the study area may be original Neoproterozoic topography, as evidenced by a possible correlation between Swift Run Formation isopach and underlying basement structural contours. The northeast trending structural and isopach contours may be anticlines and synclines created during Paleozoic folding events.
